Compiled around the 15th Century in Munich, Germany (and under ''secret'' conditions, of course) ''The Munich Manual of Demonic Magic'' was a Grimoire which provided various spells and invocations dealing with Demonology and Necromancy. It was possible a Germanic version of the earlier ''Lessor of Solomon''. Seen as a powerful ''tool'' in it's day the very possession of a copy was instant Excommunication and (no doubt) a reason for a ''visit' by the local Inquisition. It's ''Compiler'' is unknown (for obvious reasons!). Copies have been re-printed in both German and English Versions (as late as 2019).
